Library for direct userspace use of RDMA (InfiniBand/iWARP)

libibverbs is a library that allows userspace processes to use RDMA
"verbs" as described in the InfiniBand Architecture Specification and
the RDMA Protocol Verbs Specification. iWARP ethernet NICs support
RDMA over hardware-offloaded TCP/IP, while InfiniBand is a
high-throughput, low-latency networking technology. InfiniBand host
channel adapters (HCAs) and iWARP NICs commonly support direct
hardware access from userspace (kernel bypass), and libibverbs
supports this when available.

For this library to be useful, a device-specific plug-in module
should also be installed.
